Shock-absorbing low-noise long cylindrical roller bearing

The utility model relates to a damping low-noise type long cylindrical roller bearing which comprises a bearing outer ring, a bearing inner ring, a long cylindrical roller and a roller retainer, the long cylindrical roller is embedded in a roller pocket hole of the roller retainer, and the long cylindrical roller and the roller retainer are assembled in a roller path formed by corresponding rollerpath surfaces of the bearing outer ring and the bearing inner ring. The bearing outer ring is of a hollow structure, an inner cavity is filled with damping sound-absorbing foam, sound-absorbing cotton slivers are axially arranged on the inner surface and the outer surface of the interval portion of the adjacent roller pockets of the roller retainer, and the sound-absorbing cotton slivers are notin contact with the raceway surfaces of the bearing outer ring and the bearing inner ring. Through reasonable, ingenious and simple design, the shock-absorbing low-noise type long cylindrical roller bearing achieves excellent
